KABUL, Afghanistan (AP) — Taliban suicide bombers assaulted a joint U.S.-Afghan air base in eastern Afghanistan early Sunday, detonating explosives at the gate and sparking a gunbattle that lasted at least two hours with American helicopters firing down at militants before the attackers were defeated.

Taliban spokesman Zabiullah Mujahid said they first exploded a car bomb at the entrance of Jalalabad Airfield then stormed into the base. A spokesman for the Afghan Defense Ministry, Gen. Mohammad Zahir Azimi, confirmed that car bombs were used at the gate but said none of the militants were able to enter. The NATO military coalition also described it as a failed attack.

“We can confirm insurgents, including multiple suicide bombers, attacked Jalalabad Airfield this morning. None of the attackers succeeded in breaching the perimeter,” Lt. Col. Hagen Messer, a spokesman for the international military coalition, said in an email. He said that the fighting had ended by mid-morning and that reports showed one member of the Afghan security forces was killed. Several foreign troops were wounded, but Messer did not give any numbers or details.

“The final assessment of what happened this morning is not yet complete, but initial reports indicate there were three suicide bombers,” Messer said.
